I dunno my ICT has everything I want in a fatbike. 197mm rear spacing, room for over 5" tires, the 44 headset standard, 100mm BB, lots of bosses to mount stuff for when I finally take it bikepacking. The geometry with a mastodon pro is the perfect combination of rowdy trail bike and forest trekking/exploration bike.
It's not so heavy that I'd notice even on steep hills. I'll wheelie before the weight becomes an issue.
the nice thing about Surly is that they make large sizes. The XL ICT was one of the only available fatbikes that fit me. And there aren't that many fatbike models that have sizes for me anyway.
